Abstract

Maize is one of the characteristic species in Shanxi Province. It has strong drought and cold tolerance. The study of maize growth and development law through the construction of the model is helpful to accurately understand the growth characteristics of maize, improve the yield, and further provide an important theoretical basis for the realization of precision agriculture. In this paper, "Xianyu 335" maize was taken as the research object. The data of leaf length, leaf width, stem length, stem number and tassel length, as well as leaf, stem, tassel, ear, cob and root organ morphology and biomass of maize during the whole growth period were obtained by field experiment. The maize geometric form structure module was constructed. The dynamic simulation of maize growing process was realized by object-oriented programming in Visual Studio software platform. With the help of 3D OpenGL graphic library Nurbs (Non-Uniform Rational B-Splines) curve and surface simulation technology, the growth visualization of maize organs was realized based on the idea of curve and surface control point selection parameter modeling.

Abstract in Chinese

玉米是山西特色物种之一,具有很强的耐旱性与耐寒性等特点。通过构建模型对玉米生长发育规律研究有助于精准了解玉米生长特性,提高产量,进一步为实现精准农业提供重要的理论依据。本文以“先玉335”玉米为研究对象,采用田间试验获取玉米全生育期叶片数、叶长、叶宽、节间长、节间数、果穗长,以及叶片、节间、果穗、根器官形态与生物量试验数据,构建玉米几何形态结构模块。采用面向对象的程序设计,在Visual Studio软件平台实现玉米生长过程动态模拟。基于曲线曲面控制点选取参数建模思想,借助3D OpenGL 图形库Nurbs(非均匀有理B样条曲线,Non-Uniform Rational B-Splines)曲线曲面模拟技术,实现玉米各器官生长的可视化。
